How to distinguish between hard shell lithium battery and soft package lithium battery

Mainly refers to the material of the lithium battery shell. If it is packaged on the outside, it is not easy to see it. It must be seen that the battery body, the weight of the steel shell battery will be more important than the same volume of battery, but the aluminum shell and the soft packaging are not easy to distinguish. However, the soft packaging battery will be a little softer than the aluminum shell battery, and it is easy to deform by hand(do not try

Lithium batteries are just liquid lithium-ion batteries coated with a polymer shell. In the structure of aluminum plastic film packaging, in the event of safety hazards, the flexible battery will only crack the gas.

Advantages of Soft Package Battery Editing     

1. Good Safety Performance

Soft pack batteries do not explode like steel shell aluminum shell cores.

2. Light weight

The weight of the flexible battery is 40 % lighter than that of the same capacity lithium steel shell and 20 % lighter than the aluminum shell battery.

3. Large capacity

Soft pack batteries have a capacity of 10 to 15 % higher than steel shell batteries of the same size and 5 to 10 % higher than aluminum shell batteries.

4. Small internal resistance

The internal resistance of the soft-pack battery is smaller than that of the lithium battery. At present, the internal resistance of the domestic soft-pack battery core can be below 35mΩ, which greatly reduces the battery's self-consumption.

5. Flexible design

The shape of the soft pack battery can be customized according to the customer's needs and a new type of core can be developed.

The existing soft pack battery core models are few and can not meet the market demand;

Developing new models is expensive.
